(BTU base ➔ kW) INFORMATION FOR THE AIR CONDITIONER WITH R410A REFRIGERANT • This room air conditioner adopts HFC refrigerant (R410A) which never destroys the ozone layer. • Pay particular attention to the following points, though the basic installation procedure is same as that for R22 conditioners. 1 As R410A has working pressure approximate 1.6 times as high as that of R22, some special tools and piping parts/ materials are required. Refer to the table below. 2 Take sufficient care not to allow water and other contaminations to enter the R410A refrigerant during storage and installation, since it is more susceptible to contaminations than R22. 3 For refrigerant piping, use clean, pressure-proof parts/materials specifically designed for R410A. (Refer to 2. Refrigerant piping.) 4 Composition change may occur in R410A since it is a mixed refrigerant. When charging, charge liquid refrigerant to prevent composition change.

Some R22 tools can be substituted for R410A tools. The diameter of the service port on the stop valve in outdoor unit has been changed to prevent any other refrigerant being charged into the unit. Cap size has been changed from 7/16 UNF with 20 threads to 1/2 UNF with 20 threads. R410A tools Gauge manifold No Charge hose No Gas leak detector Torque wrench Description Can R22 tools be used? R410A has high pressures beyond the measurement range of existing gauges. Port diameters have been changed to prevent any other refrigerant from being charged into the unit. No Hose material and cap size have been changed to improve the pressure resistance. Dedicated for HFC refrigerant. Yes 6.35 mm and 9.52 mm No 12.7 mm and 15.88 mm Flare tool Yes Clamp bar hole has been enlarged to reinforce the spring strength in the tool. Flare gauge Vacuum pump adapter Electronic scale for refrigerant charging New Provided for flaring work (to be used with R22 flare tool). Provided to prevent the back flow of oil. This adapter enables you to use vacuum pumps. It is difficult to measure R410A with a charging cylinder because the refrigerant bubbles due to high pressure and high-speed vaporization New New No : Not Substitutable for R410A Yes : Substitutable for R410A 3 OB381A--1.qxp 10.5.25 9:28 AM Page 4 2.Refrigerant piping 1 Specifications Use the refrigerant pipes that meet the following specifications. Outside diameter Pipe mm Wall thickness 6.35 0.8 mm 9.52 0.8 mm Heat resisting foam plastic 12.7 0.8 mm Specific gravity 0.045 Thickness 8 mm 15.88 1.0 mm For liquid For gas Insulation material • Use a copper pipe or a copper-alloy seamless pipe with a thickness of 0.8 mm (6.35, 9.52, 12.7), 1.0 mm (15.88). Never use any pipe with a thickness less than 0.8 mm (6.35, 9.52, 12.7), 1.0 mm (15.88), as the pressure resistance is insufficient. 2 Flaring work and flare nut Flaring work for R410A pipe differs from that for R22 pipe. For details of flaring work, refer to Installation manual “FLARING WORK”. Dimension of flare nut Pipe diameter mm R410A R22 6.35 17 17 9.52 22 22 12.7 26 24 15.88 29 27 3.Refrigerant oil Apply the special refrigeration oil (accessories: packed with indoor unit) to the flare and the union seat surfaces. 4.Air purge • Do not discharge the refrigerant into the atmosphere. Take care not to discharge refrigerant into the atmosphere during installation, reinstallation, or repairs to the refrigerant circuit. • Use the vacuum pump for air purging for the purpose of environmental protection. 5.Additional charge For additional charging, charge the refrigerant from liquid phase of the gas cylinder. If the refrigerant is charged from the gas phase, composition change may occur in the refrigerant inside the cylinder and the outdoor unit. In this case, ability of the refrigeration cycle decreases or normal operation can be impossible. However, charging the liquid refrigerant all at once may cause the compressor to be locked. Thus, charge the refrigerant slowly.

Attach at least 2 sets of wet and dry-bulb thermometers to the indoor air inlet as shown in the figure, and at least 2 sets of wet and dry bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where air speed is high. 2. Attach at least 2 sets of wet and dry-bulb thermometers to the outdoor air inlet. Cover the thermometers to prevent direct rays of the sun. 3. Check that the air filter is cleaned. 4. Open windows and doors of the room. 5. Press the EMERGENCY OPERATION switch once(twice) to start the EMERGENCY COOL(HEAT) MODE. 6. When system stabilizes after more than 15 minutes, measure temperature and take an average temperature. 7. 10 minutes later, measure temperature again and check that the temperature does not change.

CAUTIONS ON TROUBLESHOOTING 1. Before troubleshooting, check the following: (1) Check the power supply voltage. (2) Check the indoor/outdoor connecting wire for mis-wiring. 2. Take care the following during service. (1) Before servicing the air conditioner, be sure to turn OFF the main unit first with the remote controller, and then after confirming the horizontal vane has completely closed, turn OFF the breaker. (2) Be sure to unplug the power cord before removing the air inlet grille, the front panel, the cabinet, the top panel and the electronic control P.C. boards. (3) When removing the electronic control P.C. board, hold the edge of the board with care NOT to apply stress on the components. (4) When connecting or disconnecting the connectors, hold the housing of the connector. DO NOT pull the lead wires. 3. Troubleshooting procedure (1) First, check if the OPERATION INDICATOR lamp on the indoor unit is flashing on and off to indicate an abnormality. To make sure, check how many times the abnormality indication is flashing on and off before starting service work. (2) If the electronic control P.C. board is supposed to be defective, check the copper foil pattern for disconnection and the components for bursting and discoloration. (3) When troubleshooting, refer to 11-2. “Instruction of troubleshooting”. 25 OB381A--1.qxp 10.5.25 9:29 AM Page 26 11-2. INSTRUCTION OF TROUBLESHOOTING Start Indoor unit operates.
